Hi there, Both my kids were hospitilised with Bronchiolitis, one at 5 weeks and one at 3 weeks. It is awful watching them struggle so you have my sympathy. I bought a Vicks Hot steam vaporiser which was great at the time, (think you can get them on Amazon) and is still going 7 years later! I definately found elevating the mattress slightly at the head end helped. Both of them are really healthy now (touch wood) and have no side effects! Good luck.
